The present invention relates to ring winding machines known per se comprising a radially divided winding ring and a similarly divided storage ring; it serves to wind ringshaped closed bodies. F or this purpose, both the storage and the Winding ring are passed through the body to be wound and are then provided with winding material. By rotating the winding ring, the material is passed over to the body to be wound.- In order to find room on the winding ring for the entire relatively large qnantity of wire required for winding one article, this ring generally will have a larger diameter than the ring to-be wound; hence the center of the latter must be placed eccentrically to that of the winding ring. In order to avoid forming a loop therby with the free end' of the wire, the storage and winding rings are separately driven and are mounted on rollers so that they can rotate with respect to each other.

The cross section of the storage ring plus that of the winding ring is limited by the free cross section of the ring already wound. For a'given quantity of wire, the cross section of the storage ring can be reduced by increasing its diameter, but for technical reasons this can only be done within certain limits. With increasing quantity of wire and reduced diameter of the ring to be wound, there is greater difliculty in finding room for all the wire required for one winding. This renders it necessary to repeatedly wind wire (on the storage ring).

The present invention consists in a means for overcoming this difliculty by considerahly increasing the carrying Capacity of the storage ring. In addition to the usual storage, an auxiliary storage ring made in two or more paris is provided, which can be taken' off after the wire on it has been exhausted; thus the cross section of the storage ring is reduced as the clear diameter of the ring to be wound becomes smaller. The winding operation is thereby not intcrrnpted.

The drawings show one Construction of a winding ring with storage ring as an example of the invention.

Fig. 6 shows the wire guide alone without roller.

The ring winding machine shown in the drawings comprises the winding ring 1, the storage ring 2, and the auxiliary storage ring 3, which are divided radially. The radial sections of storage ring 2 may be Secured to gether in any suitable manner, for example, by means of olamps. In order to render the storage ring 2 easily movable on the winding ring 1, the latter is provided with rollers 5, on which the storage ring 2 runs. The winding ring l is driven by a gear wheel (not shown), which engages the teeth 6 and a second gear wheel engages the teeth 7 of the storage ring 2. The second storage ring can be fixed to the first by means of screws 8 and 9 and fixing slots 9'; the letter enable the auxiliary storage ring to be quickly assembled. The wire guide i is fixed to the winding ring 1; it comprises a plate 15 and a piece 10 fixed thereto.. The letter contains the actual wire guide 11 and a hole for the roller 12. A cover plate 13 prevents the wire jumpi ng off the roller. The wire guide 4 and the roller 12 are fixed to a lever 14 or the like, which is moved into the "position shown dotted in the Fig. 4 after the auxiliary storage ring has been removed."

A modification of the storage ring with its auxiliary storage ring is that shown in Fig. 5. By' reference to Fig. '5 it will be noted that the auxiliary storage ring 3' is complete in its self. The shape of the storage ring 2' varies slightly from that of storage ring 2 of Fig. 2 to provide a suitable method of mounting the auxiliary storage ring 3' by means of screws 8'.

the rollers 5' and gear teeth 6' which corre-' The winding ring 1' has spend with rollers 5 and 6 'of Fig. 2. The stora e ring 2' has the teeth 7' which correspon with the teeth 7 of F i 2. The wire guide comprising the lever 14 the plate 15',

' the roller 12', and the piece 10' aflixed to the plate 15', is identical with the one shown in the other figures. i v

What is claimed is 1. In a winding machine for winding 1. 'closed ring-shaped bodies, a windng ring, a

material storage 'ring movably mounted about the periphery of said winding ring, and an auxiliary storage ring mounted on said material storage ring to form a larger 15 Capacity material carrier, said rings inserted 4 in the open part of the bod to be wound and said auxiliary ring remove le from the material storage 'ring to decrease'the size of the material carrier as the open space of the body 'being wound decreases without severing the material. I I

2. In a'ring winding machine, a winding ring, a sectional material stora e ring movably mounted about the perip er of said' winding ring, said storage ring. aving a guide for carrying the material from the ring mounted on the winding ring, certain V sections of the storage ring removable to decrease the size of the storage ring, saidguide adjustable' to a-new position when the sections are removed to guide material from the reduced storage ring without *severing the material; 4

In witness whereof, I hereunto subscribe my name this 19th dav of April, A. D; 1928.
